To all whom it may concern: tion with the adjacent vertical pipe. The

Be it known thatI,BURDETTE JOHN WHITE, upper fitting of each vertical pipe is also cona citizen of the United States, residing at nected with the fitting of the corresponding Westfield, in the county of Hampden and pipe on the opposite side of the mouth by a 5 State of Massachusetts, have invented certain horizontal pipe 5. The horizontal pipes exnew and usefullmprovements in Feed-Water tend across the'top of the month just below Heaters and Furnace-Mouth Protectors, of the arch-plate 6. The vertical and horizontal which the following is a specification. pipes form practically three square arches,

This invention relates to an apparatus one back of the other in each mouth. The .69 IO which is designed to be located in the mouth lower fitting'of each vertical pipe rests upon of a steam-boiler furnace for the purpose of the base-plate 7, and connected with each protecting the plates about the mouth from of these fittings and extending downwardly the intense heat of the fire in the furnace and through the base-plate into the ash-pit Sis a which at the same time may be utilized for pipe 9. The lower end of each of these pipes t5 heating feed-water. may be provided with a cap 10 or a valve 11.

The object of this invention is to provide By simply removing the caps and opening an apparatus of this nature which is cheaply the valves all sediment can be blown from the constructed and easily placed in position, vertical pipes, so that they may be easily kept which effectively reduces the temperature of clean to allow a free circulation of water. 20 the plates in the mouth of the furnace and When the apparatusis arranged foraboiler efliciently heats the feed-water, which will with adouble fire-opening, as illustrated, the not become cracked or-leaky by reason of eX- middle pipe on the inside of one opening may pansion and contraction, and which can be be connected with the middle pipe on the inquickly cleaned, so as to insure a free circulaside of the other opening by a horizontalpipe 2 5 tion and maximum efficiency at all times. 12. This allows communication from the The embodiment of the invention that is lower part of one arch to the lower part of the illustrated has pipes arranged vertically inother arch of the apparatus. A pipe 13 leads side of each fire-door adjacent to themouth from the lower part of the boiler to one of cheek-plates, pipes arranged horizontally bethe lower fittings of one arch, preferably the 5o tween the vertical pipes below the mouth fitting at the lower end of the inmost vertiarch-plate, pipes extending from the vertical cal pipe. This pipe may, however, lead from pipes through the mouth base-plate into the a hot-well, pump, or any other source of supash-pit, and connections with the boiler for ply rather than the boiler, if desired.

The cooler water 50 also coupled together, so that eachvertical then drops through the threefpipes on the pipe is at the bottom and top in communicaother side, while the warmer water flows upwardly through the outlet-pipe to the boiler. The cooler water that drops to the bottom of the first arch crosses over to the next arch and flows upwardly and across in a similar manner and when sufiiciently heated rises to the boiler.

All of the fittings used in the construction of this apparatus may be made of the same material as the pipes, so that the expansion and contraction of all will be equal, and all of the fittings and the pipes may be made of malleable iron, so that there will be no tendency to crack under variations of temperature. These parts can be readily procured and can be easily assembled originally or can be readily replaced if one part becomes damaged by any steam-fitter.

The pipes can be kept free from sediment and rust by simply unscrewing the caps at the lower ends of the pipes that project from the vertical pipes into the ash-pit, so that a free circulation is secured at all times. Thus not only will the temperature of the pipes and fittings and of the adjacent plates be kept even and moderate, but the water will be uniformly heated. This insures long life to the parts and effects an economical use of fuel.

I claim as my invention- 1. A feed-water heater and furnace-mouth protector comprising vertical pipes adjacent to the cheek-plates, horizontal pipes connecting the vertical pipes below the arch-plate and pipes projecting from the vertical pipes through the base-plate into the ash-pit, substantially as specified.

2. A feed-water heater and furnace-month protector comprising vertical pipes adjacent to the cheek-plates, horizontal pipes connecting the vertical pipes below the arch-plate, connections between the upper ends and between the lower ends of the adjacent vertical pipes, and pipes projecting downwardly from the vertical pipes through the base-plate into the ash-pit, substantially as specified.

3. A feed-water heater and furnace-mouth protector comprising vertical pipes adjacent to the cheek-plates, malleable-iron fittings at the top and bottom of the vertical pipes, couplings connecting the fittings at the bottom and couplings connec'tingI-he fittings at the top of the adjacent vertical pipes, horizontal pipesconnecting the fittings at the top of the vertical pipes with the fittings of the opposite vertical pipes, pipes extending from the fittings at the lower ends of the vertical pipes through the base-plate into the ash-pit, and pipes connecting a lower fitting on one side and an upper fitting on the other side with the boiler, substantially as specified.
